Windows NT can display a message box with the caption and text of your choice before a user logs on. Many organizations use this message box to display a warning message that notifies potential users that they can be held legally liable if they attempt to use the computer without having been properly authorized to do so. The absence of such a notice could be construed as an invitation, without restriction, to enter and browse the system. The log on notice can also be used in settings (such as an information kiosk) where users might require instruction on how to supply a user name and password for the appropriate account.
